IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 118,192, dated August 22, 1871; antedated August 21, 1871.

To all whom it may concern:

Beit known that I, GOOLIDGE B. BROWN, of Placerville, county ot' El Dorado, State of California, have invented an Improved Vapor-Burner for Gas-Generating Lamps; and I do hereby declare the following description and accompanying drawing are sufficient to enable any person skilled in the art or science to whiclrit most nearly appertains to make and use my sa-id invention or improvement without further invention or experiment. f

My improvement relates to that class Ot' burners which is employed for generating and burning gas in what is known as the self-generatin ggas lamps, and in which gasoline, naphtha, or other light hydrocarbon is employed as a burning-duid, and it consists oi' a regulating-screw which passes down through the top Ot' the cap of the burner and into an opening in the inverted cone by means Otl which the tlow of gas is regulated, in combination with a conical plug which iits into the upper end ot' the tube, and which, by becoming heated, will greatly aid in the conversion of the *apors into gas before it reaches the reservoir from which it is i'ed to the iiames. I do not claim broadly either of these devices when separately used.

In Order tO more fully explain my invention, reference is had to the accompanying drawing forming a part of this specilication, in which- A represents the generatingtube, upon the upper end of which the biu'ner or cap B is screwed. This tube is usually filled with cotton or other fiber, which conveys the Oil by capilliary attraction from the lower end, against which it is forced by the pressure of Oil in the reservoir up to the burner, where it is convertedinto gas. Instead of packing this tube with cotton, I use either wholly or partly the mineral called asbestus. This substance is fibrous in texture, and

when packed in the tube will serve to raise the oil in the same manner as the cotton, and, being indestructible by heat, it forms a permanent packing for the tube. I prefer to pack the lower half ofthe tube with cotton and the upper half with asbetus, so that when the asbetus has become heated it will greatly aid in converting the Oil into vapor. In the upper end otl the tube I insert an inverted conical plug, d. The upper end of this plug is hollow, as shown, and small holes c connect this hollow portion with the outside below the shoulder j. The apex oi' this conical plug is inserted into the tube A, and extends down into the asbestus packing, the plug being inserted far enough to bring the small holes c down into the tube, so that the vapor can pass through them into the hollow of the cone, and thence into the reservoir above. Through the top ofthe cap B passes ascrew, g, the lower end of which, when the screw is partially down, enters the hollow in the cone (l, and limits the supply of gas according to the space left between the two.

By thus constructing the burners of ,vaporlamps, the oil will be subjected to sufficient heat in the burner-tube to convert it into gas before it goes to the reservoir; the asbetus will provide a permanent, neat, and ei'lective packing 5 while the regulating-screw permits of a ready adjustment ofthe amount of gas it is desired to supply to the iiames.

Having thus described my invention, what I cla-im and desire to secure by Letters Patent, 1s-

The regulating-screw g, in combination with the hollow conical plug d with its communicating-hole e, substantially as and for the purpose set forth.

In witness that the above-described invention. is claimed by me I have hereunto set my hand andseal.
